Pregunta newbie ... este motor y demasas se puede instalar en una hiliux, con mecanica y demases standar? de ser asi hay que modificar algo? cuanto saldria el que quede 100% funcional??

esop ... gracias

Re: MOTOR vortec 4.3 v6 completisimo "FOTOS"
 

De que se puede , se puede, por tamaño , diferenciales.. etc no habria problemas, pero no es llegar y poner, habria que entrar a jugar un poco... realmente no sabria decirte cuando te puede costar la instalacion

tienes que hacer un flange para la union de la caja y motor aprox 50.000 mas el volante de inercia mecanico, 90.000 aprox, comprar la prensa cambiar el centro del estrias del disco de embrage de la hilux al original del motor y eso mas menos eso es

Re: MOTOR vortec 4.3 v6 completisimo "FOTOS"
 

Este es un Vortec TBI o Vortec MPFI?

al parecer por la foto es TBI.

Re: MOTOR vortec 4.3 v6 completisimo "FOTOS"
 

lo mismo me gustaria saber... como identifico cual es??

Re: MOTOR vortec 4.3 v6 completisimo "FOTOS"
 

Ese motor no es el L35? version Baby del LT1??

Segun entiendo CPI,

GM Port Injection
GENERAL

The following information on GM Port Injection and GM Tuned PortInjection Systems has been compiled from GM published material andas a result of discussions with our technicians who have installed these systems on a variety of vehicles. It is to the best of our knowledge accurate.

HISTORY OF GM PORT INJECTION


The first production TUNED PORT INJECTION (TPI) appeared on General Motors vehicles in 1985. The GM vehicles built with these systems were Corvette, Pontiac Firebird & Trans AM, and the Chevrolet Camaro. These systems according to the manufacturer rendered up to 30 % improvement in Horsepower, torque and economy over carbureted systems, Independent labratories conducted numerous test on the TPI systems and indicated these claims were conservative and that increases of up to 35% in these three areas are attainable.


The 350/5.7L engines from the factory went from 205 HP (1984 Corvette/ crossfire injection) to 245 HP with the addition of TPI. The only differences were the addition of the TPI (1985) and improvements in the valve train (1987). Note that this is a 20% improvement over another proven form of fuel injection.

Several modifications have been made to the TPI system introduced in 1985. The 1985 system used a GM Part #1226870 ECM and had a Mass Air Flow (MAF) sensor and a MAFS module to control the power and burnoff functions for the MAFS. In 1986 two relays replaced the MAFS module and the Electronic Control Module (ECM) was changed to a GM part #1227165. In 1989 the cold start injector was deleted from the system. The primary injectors were used for cold starts via a fuel enrichment program in the newer EPROM calibrators. In 1990 GM introduced the speed density system. In essence the MAFS was replaced with a Manifold Air Pressure(MAP) Sensor. This system uses a ECM GM Part #1227727 for the Corvette.

Another fuel system was introduced in 1992 called Central Port Injection (CPI) and appeared first on the 4.3L (W) L35 Engine. This system is the equivalent of TPI for the V6 and will increase horsepower and torque by a factor of 20% over TBI. A 30 % increase in horsepower, torque and fuel economy is seen over carburetion.

The LT1 was also introduced in 92, as the basic engine in the Corvette. It appeared in the Firebird, Z28 (F Body Cars), Caprice, Buick and Cadillac in 93. 1993 was the last year for EPROM's in these cars. Opti-Spark also made its entry on the LT1 engine in 92.

In 94, OBDII or EEPROM, computers were first used in the Corvette and F Body Cars. This was the 1st year for Sequential port Injection in these cars.

In 96 the LT4 appeared in the manual trans Corvette, it is rated at 330 HP and 340 lb ft torque. It looks the same as the LT1, however the heads and valve train have been modified. The valves are larger 2.00 Int / 1.55 Exh from 1.94/1.50. Air passages are larger to enhance volumetric efficiency, hollow valve stems, aluminum roller rocker arms and stronger valve springs have also been added. The camshaft has more lift and a slight overlap at the end of the combustion cycle eliminating the need for EGR. The compression ratio is (Premium Gas Only) 10.8:1 compared to the 10.4:1 LT1. This engine makes 330HPat 5800 RPM and 330 lb ft Torque at 4500 RPM.
We flowed the heads on both the LT1 and LT4. LT1's flowed 195 CFM compared to 240 CFM for the LT4.

Ported LT1's also flow 240 CFM. Porting the LT4 will render 272 CFM.


For 96 all Chevrolet engines are Sequential Port and are equipped with On Board Dianostics Phase II (OBDII) PCM's. Sequential Central Port Injection is a standard on the 4.3L/4300, 5.0L/5000 L30, 5.7L/5700L31, and 7.4L/7400 L29 engines. What's nice about all this ?,...They will fit the old engines, but heads would also have to be changed on the 4300, 5000 and 5700 engines.
Retrofit kits are available from FIS. For Example, Sequential Tuned Port Injection or Sequential Central Port, both systems are available from FIS.

Other Technological mods include Cam Sensor / Crank Pos Sensors in lieu of distributors. EEPROM Computers, Vortec Heads, Mass Air Flow Sensor, Roller Cams / Roller hydraulic lifters come with all engines. Retrofit kits are now available, from FIS, for Sequential Port Injection which will fit the SB, BB and the 90 degree V6 GM Engines.

TPI, SFI, MPFI, TBI, and CPI Variations
dave8412 Jun 16 2006 - 10:33am
Q: What is the difference between TPI, SFI, MPFI, TBI, and CPI injection?

A: TPI (Tuned Port Injection) is a "batch" fire system (from the factory) which means that each bank of injectors will fire all at the same time. SFI (Sequential Fuel Injection) is sequential in that only the injector that needs to fire does so. Both TPI and SFI have injectors located in every runner of the intake manifold. MPFI (Muti-Port Fuel Injection) has one injector per cylinder for more power and precise amounts of air and fuel delivered directly to each cylinder via fuel rails. However, there are more parts to wear or break. TBI (Throttle Body Injection) has two injectors placed over the throttle body (carb bowl type unit) indirectly injecting through the intake manifold. This result in less power and imprecise amounts of air and fuel delivered to the cylinders, but there are less parts to wear or break. CPI (Central Point Injection) is a hybrid of MPFI and TBI in that there are two injectors placed over throttle body sending more precise amount of air and fuel to the cylinders through a direct injection via a plastic tube and poppit valve at each cylinder. There are less parts to wear or break this way.
